hughes.net filtering content for spam

A week or so back I presented this forum with an SMTP Server Error: 554,
Error Number: 0x800CCC6F that I was getting when I tried to send spam
reports (quick or otherwise) to SC through SMTP.hughes.net using OE as my
mail client.

After much VERY painful dialogue with various (way too many) hughes.net
support staff I finally got somebody who should know to admit to the fact
that hughes.net was filtering both outgoing and incoming email content and
flat refusing to send on mail it identified as spam.  This filter is
trapping my spam reports containing the spam as .eml attachments under these
criteria and giving me the message described above.

Lucky for me I have other smtp paths through which I can report spam to SC.
It is an interesting situation though.

I don't use my hughes.net incoming mail account so I don't really "benefit"
from the service, instead I'm just hampered from reporting spam through
their smtp server to SC that I happen to get through other incoming paths.
